In naming Henry Kissinger to direct a comprehensive examination of the government's failure to prevent the Sept. 11 attacks, President Bush has selected a consummate Washington insider. Unfortunately, his affinity for power and the commercial interests he has cultivated since leaving government may make him less than the staunchly independent figure that is needed for this critical post. Indeed, it is tempting to wonder if the choice of Mr. Kissinger is not a clever maneuver by the White House to contain an investigation it long opposed. It seems improbable to expect Mr. Kissinger to report unflinchingly on the conduct of the government, including that of Mr. Bush. He would have to challenge the established order and risk sundering old friendships and business relationships. The new inquiry will be undone if the 10-member panel is hesitant to call government organizations and officials to account. There can be no place for the kind of political calculation and court flattery that Mr. Kissinger practiced so assiduously during his tenure as Richard Nixon's national security adviser and secretary of state. Nor is there any tolerance for the kind of cynicism that Mr. Kissinger applied to the prosecution of the Vietnam War.
